Switching diodes are divided into ordinary switching diodes, high-speed switching diodes, high-speed switching diodes, low-power switching diodes, high back-voltage switching diodes, silicon voltage switching diodes, etc.
1. Ordinary switching diode
Commonly used domestic ordinary switching diodes are 2AK series germanium switching diodes.
2. High-speed switching diode
The reverse recovery time of high-speed switching diodes is shorter than ordinary switching diodes, and the switching frequency is faster.
Commonly used domestic high-speed switching diodes are 2CK series.
Imported high-speed switching diodes include 1N series, 1S series, 1SS series (with lead plastic package) and RLS series (surface mount).
3. High-speed switching diode
Commonly used high-speed diodes are 1SS series (with lead plastic package) and RLS series (surface mount).
4. Low power switching diode
Low-power switching diodes have lower power consumption, but their zero-bias capacitance and reverse recovery time are lower than high-speed switching diodes.
Commonly used low-power switching diodes are RLS series (surface mount) and 1SS series (with lead plastic package).
5. High back pressure switching diode
The reverse breakdown voltages of high back-voltage switching diodes are all above 220V, but their zero-bias capacitance and reverse recovery time are relatively large.
Commonly used high back pressure switching diodes are RLS series (surface mount) and 1SS series (with lead plastic package).
6. Silicon voltage switching diode
Silicon voltage switching diode is a new type of semiconductor device, divided into unidirectional voltage switching diode and bidirectional voltage switching diode. It is mainly used in triggers, overvoltage protection circuits, pulse generators and high voltage output, extended time, electronic switches and other circuits .
